Where is linseed oil produced well? Is it better in the cold area?

China, Russia, Canada and Inner Mongolia are all producing areas of high-quality linseed oil, because the fatty acid unsaturation of linseed oil particles produced in cold areas at high latitudes is higher than that in warm areas, and there are fewer pests, less chemical pesticides sprayed and less pesticide residues in cold areas. At present, the well-known Ogliati linseed oil on the market is imported from Russia, and the quality of Canadian linseed oil is also good, but it is different to check whether it is genetically modified in Russia. Russian law prohibits the cultivation of genetically modified crops. The quality of linseed oil in Inner Mongolia is also good, but its popularity is slightly higher than that in Russia and Canada.
